404 error with Tomcat immediately after installation (not working out-of-box)

I am trying to follow this tutorial: http://www.youtube.com/watch?v=b42CJ0r-1to&list=PLE0F6C1917A427E96&index=1&feature=plpp_video

I cannot get past the first 5 minutes. The part I get stuck is after adding Tomcat server to Eclipse and starting the server. When I browse to localhost:8080 I just get this error:

HTTP Status 404 - /

type Status report

message /

description The requested resource (/) is not available.
Apache Tomcat/7.0.27

I am running a fresh copy of Windows 7 x64. Just downloaded latest versions of Java SDK, Eclipse EE, and Tomcat today. Can anyone provide some assistance with this? It seems like it should be simple!

Well it turns out the answer is in later in the video I linked to! The solution is to change the server location settings. Right-click Tomcat server in the Eclipse server list, and click Open. Change server location to "User tomcat installation" and then it works.
